PRINTED CIRCUIT BOARD OF MICROWAVE OVEN

摘要

PURPOSE: A printed circuit board is provided to enhance the efficiency of installation space for the printed circuit board as well as reduce the manufacturing cost with a reduction of a size of the printed circuit board by inserting a printed circuit board of a noise filter in a main printed circuit board to be incorporated. CONSTITUTION: A ground terminal of a noise filter printed circuit board is mutually connected to a ground terminal of a main printed circuit board on a printed circuit board through a printed wiring pattern(250). An alternate current output terminal of the noise filter printed circuit board is connected to an alternate current input terminal of the main printed circuit board on the printed circuit board through the printed wiring pattern(250). One terminal of an inrush resistor is connected to a terminal(222) of the power relay(220) through the printed wiring pattern(250) and the other terminal of the in-rush resistor(130) is connected to a terminal(242) of the in-rush relay(240) through the printed wiring pattern, so that the power relay(220) is connected to the in-rush relay(240).
